SAFETY-CAN FOR CONTAINING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 241,852, dated May 24, 1881.

Application filed March 14, 1881,

To all whom it may concern:

Be it known that I, ROBERT E. EVEREST, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Safety-Cans for Containing Liquids; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the drawings, Figure l is an elevation, Fig. 2 a vertical section, Fig. 3 detail views, Fig. 4 a vertical section at right angle to section in Fig. 2, and Fig. 5 a modification, of can having my invention.

The object of my invention is to provide a can for containing liquids, especially such as emit explosive gases, which embodies the following features: first, rendering the contents of the can absolutely safe from explosion by fire, and retaining the gas in the liquids; second, to prevent the contents being accidentally spilled by the upsetting of the can; third, to dispense with the necessity of removing any caps, in order to give vent or allow the con tents to flow out when desired. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which- A is a can of the ordinary shape, constructed of tin or other suitable material. In about the center of the top of the can is a filling-tube, B, which is protected internally by a cone of wiregauze, the apex thereof projectingdownwardly. In front of the filling-tube, and on the top of the can, is a spout, G, which is likewise protected internally at the juncture of the spout with the can by a similar cone of wire-gauze, the apex of which projects upward into the spout. At the back of the said filling-tube is a handle, D, on the -top of which is suitably placed a lever, E, said lever having at one end a spiral spring, a, and to the other end is attached a wire, d, which passes through-a hole, 0, on top of the can into the interior of the can, the hole 0 being also protected with wire-gauze. Connected to the end of the wire d, inside the can, is a lever, F, which lever passes under the filling-tube B, and has its fulcrum near the opening for the spout O, which opening to said spout is completely covered by a valve, G, at-

(No model.)

tached to one end of the lever F. Advantage is taken of the hole 0 on top of the can, through which the wire (1 passes, to provide a vent, and in order to prevent the ingress of air or egress of the gases when the can is not in use a small valve, 1), is arranged on one end of the lever E to cover it.

The operation is as follows: To till the can, the screw cover or cap on the filling-tube is removed and the liquid poured into the tube in the ordinary way. When it is desired to use the contents of the can, the lever E on the top of the handle is pressed down by the thumb, which simultaneously raises the valve b, thereby allowing the air to pass into the can, and opens the valve G, by means of the lever F, placed inside the can, thereby allowing the liquid contents to flow out freely. The removal of the pressure of the thumb on the lever E instantly closes the vent and the orifice at the base of the spout, and the can becomes airtight, thereby preventing the ingress of air or egress of the gases. By means of the wiregauze cones placed in the openings before described, it is impossible for flames to reach the contents of the can, and the valves, being airtight, render the can safe under all circumstances, as the contents will not run out, even if the can were accidentally upset. I trequires no corks or stoppers, as itis automatically selfsealing.

The construction of the lever E may be modified, as shown in Fig. 5, without departing from the spirit of my invention.

When it is desired to use highly-explosive liquids which emit gases freely, perfect safety is secured by the safety-valve H, which is placed on the top of the can, preferably between the inlet-tube and one of the ears, to which the hail of the can is attached the seat of which valve is also protected with wiregauze. spring, I, to keep the valve in its place, the other end of which spiral spring is secured in the interior of the can, the said spring being so adjusted that in case the contents are exposed to heat the valve H will open when the gas generated reaches a given pressure, (less than that which the can will safely bear,) thereby allowing the gas to escape and preventing the explosion of the can.

Attached to this valve is a spiral I am aware that an oil-can having a single set of instrumentalities foroperating the valves which close the discharge-spout and vent is not new; and I am also aware that an oil-can provided with a safety-valve and having wireganze for protecting its openings is not new and therefore I do not claim the mechanism hereinbefore described, broadly; but

What I do claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a can, of the lever E, fulcrumed to the handle, having at one end aspring, a, and at the other end a valve, 1), connected by means of a wire, d, passing through the hole 0, with one end of the lever F inside 15 the can, and carrying at the other end the valve G, substantially as described.

2. The combination, with a can, of the lever E, valve I), connecting wire (I, lever F, and valve G, substantially as described, and for 20 the purpose set forth.
